Rule #19 // Introduce Yourself.If you deem it appropriate to join a group of riders who are not part of an open group ride and who are not your mates, it is customary and courteous to announce your presence. Introduce yourself and ask if you may join the group. If you have been passed by a group, wait for an invitation, introduce yourself, or let them go. The silent joiner is viewed as ill-mannered and Anti-V. Conversely, the joiner who can’t shut their cakehole is no better and should be dropped from the group at first opportunity.
